Instagrammers know how to hashtag, take interesting pictures, and add just the right filter. But maybe that's not enough. Many new apps are emerging designed to upgrade your Instagram experience. Check out our five favorite apps for iPhone!

PicStitch
Make a collage of your favorite pictures. You can choose your layout, size of pictures, and edit each picture before completing the collage and importing it to Instagram. 

Instake
Like a picture on Instagram and want to save it to your phone? Instead of taking a screen capture, just download the picture with Instake. Just tap the picture to download to your camera roll. 

Afterlight
Before adding a filter in Instagram, edit your photo with Afterlight. Change the lighting of your picture or add one of the 27 adjustable filters. You can add unique frames and then import the picture to Instagram.

A Beautiful Mess
Personalize your photo with text, custom filters, and doodles. Add borders or text bubbles to your photo.  

Camera+
Upgrade your phone's camera with the Camera+ app. Take the best pictures using the apps features like a stabilizer so you get a steady shot, digital zoom to get close without losing quality, and grid to perfectly frame your pictures. You can even edit pictures in the app.
